This paper presents a numerical model for viscous-inviscid interactive computations of rotor flows. The model presented is fairly general, as it allows for both steady and unsteady calculations. The basic methodology for deriving the outer inviscid solution is a fully three-dimensional boundary element method. The inner viscous domain, i.e. the boundary layer, is described by the two-dimensional Navier-Stokes equations. For the interactive procedure a blade strip approach is used. The outer inviscid solution provides the distribution of induced velocities to be used as boundary condition for the Navier-Stokes solver. The outer solution is then updated with new boundary conditions, arising from the viscous effects. For unsteady flow calculations a time marching procedure is used. Some preliminary results are presented for the rotor blade of a wind turbine.
